In order to study of interaction effects of salt and salicylic acid, it was used two cultivars of canola (Hayola 401 and RGS). Canola seeds were provided from Lorestan Agriculture Research Center in this experiment. After culturing seeds in experimental environment, the intact seedling transferred to Hogland half-power culture in the dishes with 650ml capacity. After 24 hours, the plants were placed under different treatment with the salt and salicylic acid. Canola plants were placed in determined rooms and in the light and the dark periods 16 and 8 hours respectively in order to ventilation the dishes were airing every day. The treatments were included 75,100,150mM salt and 5μM salicylic acid. After 20 days, catalase and peroxides activity were tested in the root and leaves of plant. With respect to the results achieved in this research, it was determine that when salinity stress increased, the amount of catalase and peroxidase activity increased. This increase in the roots was more than leaves in both cultivar of canola. With adding 5μM salicylic acid in above environment, it showed the increase of catalase and peroxidase activity, so this case helps to reduce destructive effects of salinity and balance its effects.
